Description

The invention relates to a household refrigerator with a receiving space for food, which is limited by walls of an inner container. The domestic refrigerator has a, in particular rail-shaped, backing part, which is arranged on a receiving space facing away from the outside of a side wall of the inner container.

Such a configuration is for example from the WO 2011/080654 A2 known. An inner container of a household refrigerator is usually made of plastic, so that the direct attachment is limited by other components. Functional components, such as a rail extension device on which in turn other other components such as shelves or containers for food can be placed, have a corresponding weight, which then also acts on the mounting assembly. Especially in this context, it is known in the art to use such a metal-formed rail-shaped backing part in addition to this side wall to secure the separate functional component then secure and reliable and can also provide in the context that corresponding greater weight forces can be included. As a result of this backing part, a concept is thus virtually formed in which the side wall as load-bearing structure is maximally relieved and the actual main connection of the functional component to this backing part takes place.

Since the position of the functional component to be attached is important in order to be able to fully provide the functionality, it is also important that the backing part can be positioned accordingly accurately. Due to manufacturing tolerances and mounting tolerances, however, deviations may occur here that may affect the functionality of the overall system.

It is an object of the present invention to provide a household refrigerator, in which the positioning of a backing part is improved.

This object is achieved by a household refrigerator, which has the features of an independent claim.

According to a first independent aspect of the invention, a household refrigerating appliance is formed, which has a receiving space for food. This receiving space is limited by walls of an inner container of the household refrigerator. The household refrigerating appliance furthermore has a backing part, which is arranged on an outer side of a wall of this inner container facing away from the receiving space. The wall represents one of these walls which defines the receiving space, e.g. a side wall. An essential idea of the invention is to be seen in that the backing part has a receptacle. In this recording a separate from the backing part, deformable compensation element is arranged. By means of such a configuration, manufacturing tolerances of the backing part and / or the wall can be compensated with regard to a positionally accurate arrangement of the backing part and the positionally accurate arrangement of the backing part is improved. The compensating element as such thus forms a compensation element, which can compensate for such tolerances by its particular elastic deformability and yet the desired end position of the backing part is precisely adjusted and maintained. By a simple manner, namely by a specific additional element in the form of this elastically deformable compensating element, therefore, a particularly positionally accurate mounting of the backing part can be achieved.

The compensating element can be fastened in a form-fitting and / or non-positive manner, in particular in the receptacle. For example, the compensation element can be inserted into the receptacle or clamped in the receptacle. It is also conceivable that the compensation element is firmly bonded in the receptacle, for example by means of an adhesive connection. The compensating element can be held captive in the receptacle, in particular regardless of whether the backing part and the compensating element is surrounded by insulating foam. In this way, not only a precise mounting of the backing part is guaranteed, but also simplifies the assembly.

The receptacle may be formed by an edge-closed recess, e.g. a blind hole, a through hole, a slot or a groove. The receptacle may also be defined by an open-edged recess, e.g. a semicircular recess may be formed on an edge portion of the backing part. An edge-closed and continuous receptacle, e.g. a through hole, can be easily manufactured and provides a secure support of the compensation element.

It can be provided that the wall, on whose side facing away from the receiving space outside the backing part is arranged, is a side wall. For example, it may be a left or a right sidewall. The backing part can thus be provided, in particular, for holding for instance a rail extension device. However, the wall can also be a bottom wall, a rear wall or a top wall of the inner container. For example, the backing part for holding a Lighting device, a rear air duct or arranged in the inner container partition serve. In the following, the present invention will be described in relation to a side wall, on whose outer side facing away from the receiving space, the Hinterlegteil is arranged; however, the references to the "sidewall" are exemplary only and not limiting, but rather can be replaced by "wall".

It can be provided that the compensation element is a compensation ring. A compensation ring is conceivable, at least in sections (for example over a section of a longitudinal extent with respect to a longitudinal axis) or substantially or completely rotationally symmetrical. The compensating ring may in particular be provided with a circular receptacle, e.g. an annular hole, cooperate in the backing part. A balancing ring allows for easy assembly, since it is possible to form this without being applicable to the Drehausrichtung with respect to its longitudinal axis.

It can be provided that the compensation element is made of plastic. This makes it easy, for example as an injection molded part, in one piece. On the other hand, it is weight-minimized by this design. Not least by this material embodiment, he has an insensitivity to strong temperature fluctuations and / or humidity fluctuations. Especially the embodiment of plastic then also allows the desired elasticity of at least portions of the compensating element.

It can be provided that the compensation element is a compensation ring and has axially oriented and radially resilient wings, this axial orientation and this radial suspension being considered with respect to a longitudinal axis of the compensation ring. Through these wings, the deformability of the compensation ring is formed. The compensation ring itself thus has, in particular, a plurality of individual such wings, which are dimensionally stable, in particular, but can move relative to other areas of the compensation ring, in particular a base ring, to which the resilient wings open. By such a configuration of the compensation ring is formed as such mechanically stable and allows a particularly preferred deformation concept to then achieve the positional accuracy of the backing part on the wall can.

Alternatively, the compensating element can also be formed by a body having substantially rectangular, shaped outer dimensions, in particular a plate-like body. By the compensating element has no rotation symmetrical outer contour, in particular a precisely defined mounting position can be ensured in the backing part.

It can be provided that the wall of the inner container has a receiving pin facing away from the receiving space. This coupling pin may in particular be formed integrally with the wall. The coupling pin can interact with the compensating element. In particular, the compensation element can be positively and / or non-positively connected to the coupling pin. For example, the compensation element and thus the backing part pushed onto the coupling pin and / or snapped and / or be clamped. The compensating element may in particular have a fastening receptacle for this purpose. The fastening receptacle can be formed by a through-bore and / or a blind hole. The coupling pin may extend at least partially into the fastening receptacle. If the compensation element is a compensation ring, the coupling pin can extend in the axial direction of a longitudinal axis of the compensation ring at least partially into the compensation ring. The coupling pin may extend at least partially into the receptacle or completely through the receptacle. By such a configuration, on the one hand, a reliable and reliable attachment of the backing part to the wall is made possible. For example, the backing piece can be clamped on the coupling pin. Since these coupling pins may have manufacturing tolerances, it is particularly advantageous in this embodiment, when these tolerances can be compensated by the deformable compensating body and the desired positionally accurate arrangement of the backing part is achieved on the wall. By then the compensating body contacted directly these coupling pin, especially in the version with radially resilient wings of the compensation ring can move this depending on the coupling pin according to radially, this positionally accurate adjustment of the backing part is then achieved in particular at this coupling pin advantageous.

It can be provided that the compensating ring in the circumferential direction about its longitudinal axis has a plurality of radially resilient wings equidistant from each other in this direction of rotation. This is in many ways a then preferably cylindrical coupling pin a compensation of position inaccuracies possible. Since the coupling pin as such is rigid and virtually undeformable, just by this position and shape of the compensation ring an immediate compensation of position inaccuracies is possible. The compensation ring surrounds the coupling pin on the jacket wall.

It can be provided that the coupling pin is hollow and pot-shaped. Thus, it is preferably a wall-mounted element. Due to the hollow and cup-like design of the coupling pin is as such also minimized in weight and is also multifunctional usable.

The coupling pin may have a closed bottom and the pot-like configuration may be oriented such that the coupling pin is formed open to the receiving space.

Due to the design of the coupling pin as a hollow body, it can be used multifunctionally, namely on the one hand to be able to attach it to the backing part, namely to be able to plug in particular. For example, the coupling pin can extend with its jacket wall through the passage and the compensation element and is thus encompassed by the compensation element in the circumferential direction about the longitudinal axis of the compensation element. On the other hand, the pot shape from the opposite side creates the possibility of being able to introduce another component into it. An embodiment as a multi-attachment element is achieved. Thus, it is in particular possible that the coupling pin is designed for insertion of a positioning pin, wherein this positioning pin is formed on a arranged in the receiving space separate functional component.

The backing part may have, in addition to the receptacle, at least one screw hole which is formed spaced apart from this receptacle on the backing part. The screw hole provides a further possibility of a mechanical connection, in particular with a screw, so that the mechanically stable and positionally secure arrangement of the backing part is improved and, in particular, the connection possibilities with the additional functional component to be attached thereto are increased. It is precisely through this spaced arrangement of the receptacle and the screw hole, these two connection points are locally decoupled from each other, so that the secure and mechanically stable connection is made possible at spatially separate locations. In particular, the screw hole is arranged outside the receptacle. This brings advantages of the assembly steps to be performed and on the other hand creates two separate force paths to initiate and absorb the force, so that in this regard force peaks can be avoided at one point.

It can be provided that the wall has an integrally formed with the wall Positionierkerbe extending in the screw hole and / or aligned with the screw hole. By this configuration, a pre-positioning of the backing part is improved on the wall, as well as a targeted and accurate arrangement of the backing is already made possible by the wall by the raised trained positioning notch is positioned so that it extends in the screw hole and / or with this flees. In a subsequent screwing a screw in the screw hole, in particular coming from the wall, this is then easily possible, as already by the positioning notch already the point for a fitter is recognizable, on which the screw must be screwed on the wall, on the other then, as a result, no longer has to be sought, where the screw hole is on the backing part. Through the coupling of the positioning notch and the screw hole, the screwing through of the screw hole is then automatically achieved when it is attached to the wall, from which the screw hole can not be seen then, at the positioning notch. This has significant advantages for a quick and accurate installation and on the other hand an already pre-adjustable positional accuracy of the backing part on the wall before screwing the screw.

It can be provided that the coupling pin and the positioning notch, which are preferably both formed integrally on the wall, are formed locally spaced from each other and are integrated into the wall. By this configuration, a number of components can be reduced and the positional accuracy of the coupling pin for Positionierkerbe is thereby already given unchangeable. The thus already achievable in the production of the wall positional accuracies then also bring benefits in terms of the positioning of the backing part on the wall with it.

It can be provided that the household refrigerating appliance has a separate functional component which is arranged in the receiving space and is connected indirectly and / or directly through the wall to the backing part. The functional component is, for example, a rail extension device. This rail extension device is in particular designed as a telescopic extension and has a fixed rail, which is then connected to the backing part, and know at least one running rail, which is then displaceable in the longitudinal direction of the rail extension device relative to the fixed rail. At the rail extension device, for example, a container which is designed for receiving food, be arranged. As a result, a drawer is formed, which can be pushed into the receiving space and pulled out. A related linear movement in the depth direction of the household refrigerator is thus easily possible. As in addition to the weight of the rail extraction device then also the weight of the container and possibly even occurs from introduced into the container storage goods, just the mechanically stable attachment of this functional component is of particular importance. The attachment to the wall alone is permanently not sufficient.

It can be provided that the functional component has a positioning bolt which is inserted into a coupling pin formed integrally on the wall. For example, the positioning bolt may be inserted from the receiving space forth coming into the coupling pin. The achievable advantages in this regard have already been mentioned above.

In addition, it may preferably be provided that the functional component with a screw which is screwed into the positioning notch and the screw hole, additionally screwed to the backing part. The position fixation and mechanical stability of the connection is thereby increased again.

It can be provided that, in an advantageous embodiment, at least two coupling pins and at least two positioning notches, in particular three positioning notches, are provided. In particular, the positioning notches are arranged in a row to one another and also arranged the coupling pin in a row to each other. It is advantageous if the coupling pins and the positioning notches are positioned in a single row to each other, wherein a positioning notch and then in turn a coupling pin are arranged alternately in this row.

In particular, the backing part can have three threaded passages and two passages.

In one embodiment it is provided that the receptacle is designed as a passage in the backing part in a coupling dome of the backing part. The backing part has a base plate in which the coupling dome is formed as a survey. In particular, the coupling dome has a roof in which this passage or this hole is formed. Such an embodiment improves the attachment and the passage of the compensating element, for example the compensating ring, since its position of fit and its basic support on the backing part are improved. An undesirable tilting of the compensating element is thereby avoided, since a certain trough-like receptacle is provided with a certain depth by the configuration of the coupling dome, in which the compensating element is then received and held accordingly. In addition, an increase in the mechanical stability of the backing part, in particular in the region of the receptacle, can be achieved by the coupling mandrel.

It is particularly advantageous if the compensating element, for example the compensating ring, is also locked in its inserted position in the bushing therein. An undesirable slipping or even slipping out of the compensation ring from the implementation is thereby prevented.

It can be provided that the compensating element is arranged exclusively on a side facing away from the receiving space of the wall of the inner container. In particular, it can be provided that the compensation element does not extend into the inner container.

It is preferably provided that the compensation element only serves for fastening the backing part, in particular before the introduction of insulation material in the area facing away from the receiving space.

Another independent aspect of the invention relates to a household refrigerator with a receiving space for food, which is limited by walls of an inner container of the household refrigerator. The household refrigerating appliance furthermore has a rail-shaped backing part, which is arranged at an outer side of a wall, which faces away from the receiving space and which delimits the receiving space, of the inner container. The household refrigeration appliance furthermore has a screw hole on the backing part, on which a functional component of the household refrigerating appliance, which is separate from the backing part, can be screwed on. An essential idea of this further aspect of the invention is to be seen in that spaced apart from the screw hole and thus locally different to a receptacle in the backing part is formed. In this recording, an integrally formed on the wall of the inner container pot-like and at its end remote from the receiving space closed coupling pin extends. This plug connection between the wall and the backing part is thus locally formed at a different location than a screw connection which is achieved between the functional component and the backing part by screwing a screw into the screw hole. By this local separation of a possible screw connection between the functional component and the backing part on the one hand and the plug connection between the wall and the backing part on the other hand, the positionally accurate attachment of the individual components to one another as well as a positioning to the wall can be improved. As a result of this local separation, a functionally different multiple connection structure is no longer created at one point, which can then possibly tilt or rotate, but instead by these two locally separate and functionally different types of connections here is also the position fixation and positionally accurate arrangement improved. It also remains permanently in this regard, even if corresponding forces occur during operation of the functional component, since a rotation around a single connection point, in which two different types of connection are combined, is prevented.

Embodiments of the first independent aspect of the invention are to be considered as advantageous embodiments of the further independent aspect of the invention.

In the aforementioned aspects of the invention tolerances in the production can be compensated improved in particular in the deep drawing of the wall and / or punching the backing part. It is a particularly simple mounting of the backing part allows, since it only has to be pushed onto the outside of the wall and must be fixed before introducing a thermal insulation material in a space between the inner container and an outer casing of the overall housing of the household refrigerator only with a simple tape. It is no longer necessary to turn the entire inner container. The assembly is thus less expensive and faster. In addition, a particularly simple assembly of the functional component is possible, since just in the advantageous embodiment with this positioning a targeted attachment of the functional component on the wall and thus a targeted coupling with the backing part is achieved and a preferred performed subsequent additional screwing particularly simple and can also be performed accurately. A holding of the functional component by a fitter when attaching the functional component, when the screw is set, is no longer necessary, since alone by the introduction of the positioning in the coupling pin, the functional component already holds in its position itself, so that the fitter for subsequent screws has both hands available. Just tolerances in the wall thickness of the wall can also be compensated by the compensation ring, since in this respect a relative movement to the backing part is made possible, so that a certain rich fitting seat on the outside of the wall is made possible by the compensation rings. By means of this advantageous refinement, a substantial improvement with respect to a front-side door of the household refrigerating appliance is then achieved, which, in particular as part of a drawer, is then arranged on the functional component. Since the functional components considered by itself then already extremely precise position and especially oriented horizontally, this is then true for the front door, so here unwanted tilting or uneven gaps to other front components of the household refrigerator, such as another separate and adjacent door, at least significantly reduced, in particular can be avoided.

In 1 is a household refrigerator 1 shown, which is designed for storing and preserving food. The household refrigerator 1 is in the embodiment, a refrigerator-freezer combination device. The household refrigerator 1 has a housing 2 on, in which a plurality of separate receiving spaces are formed for food. In this context is a first recording room 3 formed, which is formed in the present embodiment as a cooling compartment. In addition, the household refrigerator includes 1 in the height direction (y-direction) formed underneath fresh food compartment 4 , which is a partial volume of the refrigerator compartment 3 represents and in which a different humidity and / or a different temperature to the overlying remaining partial volume of the receiving space 3 is adjustable.

In the exemplary embodiment it is provided that the receiving space 3 can be closed by a plurality of separate, front-side arranged doors. The fresh food compartment 4 is in the context of a door 5 lockable, which is a front wall of a linearly displaceable in the depth direction (z-direction) drawer. The remaining partial volume of the recording room 3 is through two more separate doors 6 and 7 lockable, which are about vertical axes and thus oriented in the vertical direction axes separately and independently pivotable. By this configuration, on the one hand, the remaining part volume of the receiving space 3 which is not by the fresh food compartment 4 is formed, regardless of the fresh food compartment 4 be opened and closed, which by corresponding pivoting of the doors 6 and or 7 he follows. Again independent of it then can the fresh food compartment 4 be opened by the door 5 is opened and thus the drawer is pulled out.

The household refrigerator 1 also includes two additional separate recording rooms 8th and 9 that are freezers. It can also be only a freezer available.

The two freezers are also in turn by separate doors 10 and 11 closed, and here in the embodiment shown, these doors 10 and 11 Front walls of linearly displaceable in the depth direction drawers are. For example, it is shown that the lower freezer through the door 11 trained front wall of a drawer 12 lockable, this drawer 12 shown here in pulled out condition.

The recording rooms 3 . 8th and 9 are limited by an inner container, which is formed in particular from plastic, said inner container according to the illustrations in 2 Part of household refrigerating appliance 1 in the area of the lower freezer shows, oriented in the height direction side walls 13 and 14 having. When displayed in 2 is the drawer 12 pulled out, so in the interior of the freezer, which through the receiving space 9 is formed, can be looked. As can be seen, is on an inside 14a the Wall 14 (Sidewall) a rail extension device 15 arranged, which is a telescopic extension. On the opposite wall 13 (Sidewall) is a corresponding rail extension device arranged in 2 but not visible. At these oriented in the depth direction rail extension devices 15 the drawer 12 is arranged and by means of these rail extension devices 15 displaceable.

As in 1 can still be seen, the drawer knows 12 next to the front wall, which is the door 11 represents a container 16 on, which is designed to receive the food.

The functional component, in particular in the form of the rail extension device 15 , is with a separate backing part, which is formed of metal, on the side wall 14 attached. Accordingly, this is the rail extension device that on the side wall 13 is attached, provided. This is in 2 to recognize that on an outside 13b that is an inside 13a the side wall 13 opposite, a rail-shaped backing part 17 is arranged. This outside 13b is the recording room 9 turned away and an outer casing 18 ( 1 ), which is another component of the housing 2 is, facing. Between the outer casing 2 and the inner container 19 as he is in 2 is shown, a gap is formed in the thermally insulating material, in particular an insulating foam, is introduced.

In 3 is a perspective view of an embodiment of the backing part 17 shown. According to this embodiment is also the backing part 17 which is on the outside of the side wall 14 is arranged, formed. The backing piece 17 is a rail-like component, which in a sectional plane perpendicular to a longitudinal axis A of this Hinterlegteils 17 angled, in particular U-shaped, is formed. The backing piece 17 has a base plate 20 on, in which a first coupling dome 21 and locally spaced therefrom a second coupling dome 22 are formed. The coupling domes 21 and 22 are elevations that are different from the plane of the base plate 2 extend out. In particular, these coupling domes extend 21 and 22 turned away from the recording room 9 and thus also to the outside 13b on the base plate 20. The coupling domes 21 and 22 each have a hole or a passage on their coupling roofs 23 respectively 24 on.

In addition, in the backing part 17 , especially in the base plate 20 , several screw holes 25 . 26 . 27 formed, in particular, integrated in the base plate 20 are formed. The screw holes 25 . 26 . 27 have internal threads. As can be seen, the screw holes 25 . 26 . 27 arranged in a straight-line connection or in a row to one another, in particular, viewed in the direction of this row alternately a screw hole 25 . 26 . 27 and then again a coupling dome 21 , 22 or an implementation 23 . 24 educated.

In 4 is the backing piece 17 in one too 3 shown different perspective view. It is to recognize the side that in the mounted state on the outside 13b is applied.

In 5 is the backing piece 17 according to the perspective view in 3 shown. In addition, in the bushings 23 and 24 deformable separate compensation rings 28 and 29 inserted, in particular locked in it. The compensation rings 28 and 29 are thus in the coupling dome 21 and 22 introduced and extend through these bushings 23 and 24 therethrough.

In 6 is a perspective view of an embodiment of a balancing ring 28 shown. This includes a base ring 30 on which several springy wings 31 are arranged, of which the clarity serving only some are provided with the corresponding reference numerals. The balancing ring 28 is preferably a one-piece plastic part, wherein in the direction of a longitudinal axis B of the balancing ring 28 the wings 31 are axially oriented. They are in the direction of rotation about the longitudinal axis B equidistant to each other and are in the radial direction to this longitudinal axis B elastically resilient. In the embodiment, at least five, in particular seven such wings 31 educated.

As can be seen, have at least some wings 31 on its outer sides a radially outward nose 32 on, which is in particular a detent. By means of this nose 32 can the compensation ring 28 at the coupling dome 21 and in particular in the implementation 24 be locked.

In 7 is in a vertical sectional view of the balance ring 28 shown. As can be seen, are upper, free-standing ends 33 the wing 31 to the longitudinal axis B inclined so that a claw-like structure is formed. This is also a staple effect of these fingers or wings 31 formed when another element passes through the balancing ring 28 extends through and these wings 31 especially with these ends 33 then rest against this further element. A certain point force and thus improved support is achieved, especially when the wings 31 then subject to a certain radial bias.

In 8th is a partial perspective view of the side wall in a perspective view 13 shown, here on the outside 13b is looked. As can be seen, are in this outside 13b cylindrical coupling pin 34 and 35 integrally formed, extending from the outside 13b extend outwards and thus the receiving space 9 are oriented away. The coupling pin 34 and 35 are each hollow, cup-like structures that form a closed bottom 34a respectively 35a exhibit. To the recording room 9 there are these coupling pins 34 and 35 open formed so that they form quasi in this regard, a kind of cup or a blind hole.

In addition, on this outside 13b also positioning notches 36 . 37 and 38 integrated and thus integrally formed, which form a pyramidal small elevations. In particular, it is provided that the coupling pin 34 and 35 are arranged in a row to each other and also the Positionierkerben 36 to 38 are arranged in a row to each other. In particular, here too all said elements are arranged in a row to one another and positioned alternately to one another in the direction of this row.

In 9 is in a plan view and thus looked in the negative y-direction the household refrigerator 1 in the area of the side wall 13 shown. It is here the rail extension device 15 on the side wall 13 as shown in 2 is shown, shown. As can be seen, is in the mounted state of the coupling pin 34 through the implementation 23 and also through the compensation ring 28 through put. Position tolerances and / or manufacturing tolerances are here by this flexible deformability of the wings 31 balanced, so that here a rich and holding tight fit of the coupling pin 34 is given and thus the backing part 17 firm and accurate to the side wall 13 is arranged. In 9 is also this pot-shaped configuration of the coupling pin 34 shown and thus the embodiment as a hollow structure. On the recording room 9 facing side is in this coupling pin 34 a positioning bolt 39 the rail extension device 15 plugged in.

In addition, it can be seen that the in 9 Positioning notches shown 36 and 37 in alignment with the screw holes 25 and 26 are arranged and are arranged slightly dipping in this, so that here is achieved a Lagezentrierung. In addition, it can be seen that on the rail extension device 15 a coupling hump 40 is formed on the inside 13a the side wall 13 is applied. This coupling hump 40 has a hole 41 on, like this in 10 it can be seen by which a screw is made to enter the positioning notch 36 and then through it in the screw hole 25 to be screwed. The same is the case of the further coupling hump 42 provided, so again by inserting a screw through the positioning notch 37 is rotated through and into the screw hole 26 is screwed, a further screwing allows.

As can be seen, the arrangement of a screw hole 25, 26, 27 is locally different and thus spaced from one bushing 23 . 24 so that these two different connection devices are also formed locally separated from each other.

This is also in the perspective sectional view in 10 to recognize again.

As in the illustrations according to 9 and 10 can also be seen, the base ring 30 a thickness approximately at the depth of the coupling dome 21 equivalent. This is in the assembled state of the compensation ring 28 this base ring 30 not in the direction of the side wall over, so here no unwanted impairments or deformations or force effects on this side wall 13 act. In addition, this base ring lies 30 flange on the boundary wall of the implementation 23 in the coupling dome 21 on and the noses 32 lie on the opposite outside of the coupling dome 21 on. This is the locking of the balance ring 28 at the coupling dome 21 reached. Also in 10 is the local separation and spaced configuration of the screw connection between the functional component 15 and the backing piece 17 over the screw hole 25 to the connector, which is characterized by the insertion of the coupling pin 34 in the implementation 23 and through the compensation ring 28 results shown. Also, then the connector between the coupling pin 39 and the coupling pin 34 shown, which is locally separate to this aforementioned screw. Locally summarized, however, is the plug connection of the coupling pin 34 in the implementation 23 as well as the plug connection of the positioning bolt 39 in the coupling pin 34 ,
